ROBERT DUNCAN MURPHY, OF BALTIMORE, MARYLAND.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 493,107, dated March 7,1893.

Application filed November '7, 1892. Serial No. 451,171. (No model.)

To all whom it may concern:

' Be it known that I, ROBERT DUNCAN MUR- PHY, of the city of Baltimore,in the State of Maryland, have invented a new and Improved WindowFastener and Look, of which the following is a full, clear, and exactdescription.

Myinvention relates to an improvement in window fasteners and locks, andit has for its object to provide a device which will be exceedinglysimple, and capable of being applied either to a window sash or to awindow casing, and adapted for holding the window sash in whateverposition it may be placed; and the device is further applicable for looking the window sash in place when the window is in its closed position.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a face view of the device applied to a window sash andillustrating the device as holding the sash in an elevated position.Fig. 2 is a similar view to Fig. 1, the device being shown in a lockedposition, but the friction disk is shown out of engagement with Fig. 3is likewise a face view, illustrating the device in a locked position,the friction disk being in engagement with the window frame. Fig. 4 is ahorizontal section, taken essentially on the line 4-4 of Fig. 3; andFig. 5 is an edge view of the device detached from the window. a

In carrying out the invention the device consists primarily of a disk A,which is constructed entirely of rubber or a like material, or alternatelayers of rubber, canvas or other fabric, and twin hooks designatedrespectively as 10 and 11, which hooks are a portion of a common shank12, the shank being preferably of a circular form. The hooks 10 and 11,are bent outward in such manner that their inner faces, for example, arebeyond the outer face of their shank as shown in Fig. 5.

The disk A, is provided with an eccentrically located aperture, and theshank of the twin hooks is provided with a central apermm. The twinhooks are adapted to be connected with thedisk, and this is effected bypassing a screw 13, or the equivalent thereof through the aperture inthe shank of the" hooks and the aperture produced in the disk. The diskis provided with a series of peripheral teeth 14, or the periphery ofthe disk may be roughened, fluted, or serrated in any suitable orapproved manner.

I desire it to be distinctly understood that the attachment may beapplied to the Window. frame in such manner as to cause the disk, whendesirable, to bear against the window sash; or, as shown in thedrawings, the device may be applied to the window sash and the disk bemade to have bearing against the window frame.

In applying thedevice, the screw 13 after having passed through theshank of the hooks and the disk, is passed into the window sash, theapplication being so made to the sash that the disk may be thrown to anengagement with the window frame or out of engagement therewith.

The twin hooks are adapted as looking devices, and the hooks and theirshank serve to strengthen the disk or stiffen it, as is clearly shown inthe drawings. When the window is to be raised or lowered the disk iscarried out of engagement with the window frame, which may beaccomplished by manipulating one of the hooks, as the hooks will clingto the disk by reason of frictional contact. The window at that time maybe raisedv or lowered, and after it has been raised to the desiredheight the disk is thrown outward or in such direction as to cause itsperiphery to engage with the window frame, and by reason of thecocentric engagement of the disk with the window sash the weight of thewindow will cause the disk to be carried in firm locking engagement withthe frame. When the window is entirely closed it may be locked in thatposition by causing one of the hooks to enter a staple or eye-bolt 15,located in the window frame, as shown in Fig. 2, the disk at that timebeing carried entirely out of engagement with the frame; or a doublelock may secured by causing the disk to engage with the Window frame,and one of the hooks to enter the eye-bolt or staple 15, as shown inFigs. 3 and 4:- When a single lock is to be accomplished, the staple oreye bolt is made longer than when a double lock is to be secured.

It is evident that this device is not only exceedingly simple, economicand practical, but that it may be applied, as heretofore stated, eitherto a window sash or to a window frame in an expeditious and convenientmanner; and it is also obvious that the device may be manipulatedreadily and its manipulation understood by any person of ordinaryintelligence.

Having thus described my invention, I

claim as new, and desire to'secure by Letters Patent 1 As an improvedarticle of manufacture,

a window fastener and lock, the same consistrng of a diskeccentrieallypivoted, and

hooks held infrictional engagement with the disk, as and for thepurposespecified.

2. As an improved article of manufacture, a window fastener and lock,the same consisting of a disk having a roughened exterior andeccentrically pivoted, and oppositely pro- 1 j'ecting twin hooks theshank of which is pivoted correspondingly to the disk, substantially asand for the purpose set forth.

as rubber, eccentri-cally pivoted, and a looking device consisting of astiif plate shaped to form twin hooks and a common shank, the shankbeing pivoted by the same pivot pin pivoting the disk as' and for thepurpose specified.
